IM31-11EX-U中文资料图尔克数据手册PDF规格书

Normalized active voltage or current signals

are transmitted via the 1-channel analog signal isolator IM31-11EX-U.

The device is equipped with one input circuit

of 0/2…10 V or 0/4…20 mA and one short-circuit proof output circuit of 0/2…10 V.

The transmission characteristic is adjusted via

a DIP switch on the front. In switch position

1:1 the input signals are transmitted without

interference and made available at the output in the non-Ex area. In LZ switch position, a dead-zero signal at the input (0…10 V /

0…20 mA) is converted and provided as a

live-zero signal at the associated output (2…

10 V).

A green LED indicates operational readiness.
